"If somebody has a long history of hurting you, and they have a Machiavellian personality, the only thing they understand is a display of force. If that’s the case, the best way to protect yourself is to fire back with everything you’ve got. Look, some people deserve to be treated badly. More importantly, they need to be treated badly. Sometimes you have to speak to the asshole in the only language they understand, and that means you have to get your hands dirty." Robert Sutton
